- Denafrips dac-68
- Holo Spring (from Wildism Audio HK, Jensen Caps + Silver Transformer)
Impressions coming soon
Here comes the initial impressions
The Spring has been well burnt-in, whiles the DAC-68 has less than 12 hours on it. So if the difference is anything after pre- and post- burn-in differences on the Spring, there could be quite some change
Main listening gear was a pair of Stax SR-001 mk2. Source was either from PC (USB) or Fiio X5 (Coax). Since the DAC-68 is not burnt-in yet, the more serious comparisons will have to come later
When that happens, a full desktop setup will be used
.
Sound
The Spring has a wider sound-stage, and sounds more 'refined'. It also sounds more "realistic" compared to the DAC-86, i.e. things sound more like a live performance rather than a recording.
Bass is also stronger on the Spring, it's more bodied. The DAC-68 in comparison sounds slightly more lean, but the detail is around the same level. I find that a more bodied bass does give a more engaging experience, but this is purely personal preference.
The DAC-68 sounds more centered, and mid focused. Certain details tend to jump out at you, as opposed to the spring where everything is just there for you to discover. Again, this is will depend on preference.
Interestingly, I find that the DAC-68 reminds me of the Spring in OS PCM mode. So the differences might actually be more on the filters used than the architecture of the dac. So from my guess is that NOS vs OS makes more of a difference than DS vs R2R. I didn't try any DSDs, but probably will when the detailed comparisons are done. Note that DSD sounds amazing on the spring
Other Observations
- The Spring runs warm (even in standby mode), the DAC-68 runs so cool, you would not even know it had been on even after a long time.
- The DAC-68 goes into standby mode when there's no input plugged in.
- On the DAC-68, the SQ difference between USB and coax is
significant . I was shocked at how bad coax sounded. I haven't tested toslink so I don't know if that sounds any different. (unless you use a DDC
)
This difference between inputs has made me seriously consider a Singxer SU-1 for the Spring. But currently, coax and USB sounds about the same on the Spring.
- The Spring is very heavy, the DAC-68 is very light (think solid brick vs empty metal box)
TL;DR
For me the DAC-68 is not quite a Spring replacement/killer. I think this comes down to my preference of the NOS sound. Both are great products at their price points. You will get more than your money's worth on both products. Just get whichever your budget allows.
